BACKGROUND
Various ECG abnormalities are commonly observed in obesity and in metabolic syndrome.
SUMMARY
Some of these abnormalities are caused by the pushed-up position of the diaphragm due to obesity and others occur as a result of the complications of the condition. The position of the R wave may change, various arrhythmias may develop or the QT interval may be prolonged, which increases the tendency to malignant arrhythmias. In obesity, the ECG signs of ventricular hypertrophy are less informative due to the accumulation of epicardial and subcutaneous adipose tissue. In general, it can be concluded that a microcirculation disorder is present in metabolic syndrome that may primarily be associated with ST-T wave abnormalities.
KEY MESSAGES
Body surface potential mapping is a more sensitive method than traditional ECG with potentially greater use for diagnosis mainly in the early phase of non-ST elevation myocardial infarctions.
背景
肥胖和代谢综合征常伴有各种心电图异常。
概要
这些异常中的一些是由于肥胖导致的膈膜上推位置引起的，而另一些则是由于该病症的并发症引起的。R 波的位置可能会改变，可能会出现各种心律失常，或者 QT 间期可能会延长，这会增加恶性心律失常的倾向。在肥胖症中，由于心外膜和皮下脂肪组织的堆积，心电图上心室肥厚的征象不太具有提示性。一般来说，可以得出结论，代谢综合征中存在微循环障碍，这可能主要与 ST-T 波异常有关。
关键信息
体表电位图是一种比传统心电图更敏感的方法，可能主要在非 ST 段抬高型心肌梗死的早期阶段，具有更大的诊断应用潜力。
